Vadose/W Software by Avantech Engineering Consortium Pvt. Ltd.

VADOSE/W is a finite element CAD software product for analyzing flow from the environment, across the ground surface, through the unsaturated vadose zone and into the local groundwater regime. Its comprehensive formulation allows the analysis of both simple and complex problems, from a simple analysis of ground infiltration due to rainfall, to a sophisticated model considering snow melt and root transpiration as well as surface evaporation, runoff, pounding, and gas diffusion. VADOSE/W can be applied to the analysis and design of Geo technical, mining, hydro geological, agricultural, and civil engineering projects. Understanding unsaturated soil mechanics is now critical for Geo technical engineers performing slope stability analyses, designing soil covers for mine or municipal waste facilities, or determining the effect of agricultural or irrigation projects on groundwater flow. Environmental conditions at the ground surface, such as precipitation, evaporation and transpiration, have been increasingly recognized as having a significant impact on soil behavior in the unsaturated or vadose zone. In fact, “unsaturated soil mechanics may have more to do with the ground surface moisture flux conditions than it has to do with the thickness of the unsaturated soil zone” (D.G. Fredlund, Geo technical News, Dec. 2001). So how can you determine the impact of environmental conditions on the unsaturated zone? VADOSE/W provides a solution to this problem.
